WINDOW FRAME AND SASH* SPECIFICATION forming part of Letters Patent No.508,010, dated November 7, 1893.

Application filed August 4, 1892. Serial No.442,1 38. (No model.)

To all whom Il? may con/cern,.-

Beit known that I, FRANK ALBERT GOELZE, of Chicago, county of Cook, andState of Illinols,V have invented certain new and usefulImprovementsinWndow Frames and Sashes, of which the following is aspecification, reference being had to the accompanying drawings.

The object of my invention is to produce a neat, convenientfstrong, andcomparatively inexpensive window-frame,'and a' sash balanced therein andadapted to be revolved in itsbearings for the purpose of cleaning orrepalring it, or the like.

In the accompanying drawings, Figure lis a front view of my frame andsash complete. Fig. 2 is a central vertical transverse section of thesame. Fig. 3 is a view of one side of the frame and its separableweather strip in juxtaposition. fastening plate or pivot piece and it'sadjacent parts. Referring to the figures on the drawings, 1 indicates aWindow-frame, which may be made 1n any suitable manner for the receptionof sashes 2, each of which is adapted to be raised and lowered in theordinary manner.

3 indicates sash-balances of any ordinary and suitable construction, forexample as illustrated, and consisting of weights and cords passing overpulleys in the top of the frame, as usual. These parts are of wellknownconstruction and do not need special description.

The frame is made as above suggested,sub stantially in the ordinarymanner; but, instead of having its inside length or height twice that ofthe inclosed sashes, it is made of a suitable additional length, toyaccommodate a false sill 5 which may be made of suitable material,substantially as illustrated, with a face 6 for giving it a finishedappearance. This sill may be made of solid wood, as illustrated; or, forthe sake of lightness, as it has to be lifted occasionally,it may bemade of thin material, joined together to give it the appearance ofsolidity.

Suitable means are provided for holding the false sill firmly in itsposition. I prefer to use projections7 on each of the inner edges of theframe. These are provided with screws 8, which pass through projectionsand screw 'jections may be made of metal.

Fig. 4. is aview of the cord? into the face of the false sill. Theprojections may be made of wood, and may be provided with suitablebearings to prevent vthe wear of the screws; and screw-plates may alsobe provided in the face of the sill,'or the pro- These, however, arematters of mechanical construction which are not essential to myinvention.`

The sides of the frames are preferably provided with longitudinalgrooves or ways 9,

within which the nipples of the cord-plates on opposite sides ofthesashes work in practice. These plates are preferably made lof brass, orother suitable material, and consist of a base-plate lO, and aperforated nipple l1.

The base-plate is countersunk into the edge of the sash, so that onlythe nipple projects, forming a pivot-piece and guide-piece. A recess inthe sash, under the nipple, is proness, and specially for additionalsecurity when the sashes are closed, I prefer to provide, in the upperpart of the frame for the retention of the outer upper sash, permanentweather strips 14, of substantially the same length as the upper sash.This is sufficient to hold the upper sash in position, since ordinarilyit is suspended in the upper part of the frame. When lowered the nipple,as above suggested, is sufficient to hold it in place.

On the inner side of the frame I provide removable weather strips l5,and for convenience provide key-slots 16 upon the sides of the frame,and keys 17 upon the strips, or vice-versa. The key-slots may be made inany suitable manner and preferably consist of separable metal platesscrewed over recesses in the frame. The keys may consist simply ofscrews or nails with large heads fitted to the key-slots so as to retainthe strips in position. Of course any other means for detachablyfastening the strips may be employed. rIhe strips may extend from thetop of the frame to the top ot' the false '"sill, or they may bedivided, and their upper parts made permanent, in the same manner aswith the strips for the upper sash, it being only necessary that thelower parts of the strips should be removable.

At a suitable distance from the true bottom IOO of the frame I prefer toprovide, upon opposite sides of the frame, transverse channels 1S, of awidth to accommodate the free passage of the nipples of the cord-plates.The distance of these channels from the bottom of the frame should besuch as to allow the nipples to freely Work in them, so that when thefalse sill has been detached and the Weather strips have been removed,the sashes, when sufficiently lowered, may be swung upon their cords inor out of the frame.

The operation of my device will be understood from the followingdescription: Suppose the false sill and the Weather strips to have beenremoved, by lowering eitherof the sashes to a point where its nipplescome opposite the channels in the frame, it maybe Withdrawn and handledin 'any desirable manner without detaching it from its cords orfastenings. They may be rotated without removing them from the frame,merely using their cords -as pivots and revolving them in thelongitudinal grooves in the frame. It should be observed that eithersash may be handled in this manner without reference to the other. Vhenit is desired to restore them to their original positions, all that isnecessary is to lift them a suicient distance, replace the false sill,secure it, and set thedetachable Weather strips in position.

I desire it to be distinctly understood that I do not limit myself tothe exact details of construction as hereinbefore suggested, forexample, but I claim the right to vary them at will within the scope ofmy invention.

Vhat I claim is- 1. The combination with a window frame provided withlongitudinal grooves and transverse channels, of a sash provided withpivot pieces longitudinally movable therein and removable therefrom,substantially as specified.

2. The combination with a Window-frame, a detachable sill and weatherstrips, pivot pieces upon the sashes moving in grooves in the frame, andtransverse channels in the frame, substantially as and for the purposespecified.

In testimony of all which I have hereunto subscribed my naine.

FRANK ALBERT GOELZE.
